Here is the ideas for the maths we could use:

1. Finding the height of a body if a bone length is found or whether the body is male or female if height and bone length is known

EG. Find skeleton- measure femur and measure height to know if male or female.

Formulas: Male: 69.09+2.2+F=H F=femur length H=height (ref p.137 Donlen and Hodgson yr 10 Maths
Female: 61.41+2.32+F=H

See which formula works to find whether male or female

Use skeleton from science dept?

2. Length of skidmark to determine speed of car before crash.
V= 1000D
210+97R R=road surface index V=speed in kph D=length of skidmark R=0.8 for dry concrete
